The thing to keep in mind is that you really should have a KDF character in-game of high enough level to play any mission you create for that faction. Things don't always work the same in the live game as they do in test plays within the foundry.

You should always play through a mission you create right after publishing so you can withdraw it if something is amiss. A couple of bad ratings right out of the gate because of an unnoticed technical issue can bury your mission for good.
